Each of the H beams, as shown, may be made of two channel irons placed back-to-back and secured together by the angle irons 33 and bolts 34,

Base'rblock 5 rests on the bottom wall 350i a channel'iron which has side walls 36 and"?! extending upwardly along each side of block .5. Block 5 and the channel iron have similar extennel iron extension 38, 39, and. the H beams is a rubber pad or cushion Mlflandlon each bloc]; extension 38 is a rubber pad on cushioni ljl. The
